A Life of Greatness
Dr Michael Breus: Why You Wake Up at 3am (And What To Do About It)
Are you waking up in the middle of the night and unable to fall back asleep… no matter how tired you are?
In this episode of A Life of Greatness, Sarah Grynberg sits down with renowned sleep expert and sleep psychologist Dr Michael Breus to unpack the science, psychology, and hidden habits that are quietly destroying your sleep.
From anxiety and racing thoughts to hormones, heart rate, and even your genetics, this conversation reveals why so many of us struggle to get quality rest… and what we can actually do about it.
Dr Breus shares practical, science-backed tools to help you fall asleep faster, stay asleep longer, and finally wake up feeling restored. This is not about rigid rules or unrealistic routines… it’s about understanding your body and working with it.
Because when you improve your sleep… you improve your entire life.
You’ll learn:
- Why anxiety is the #1 reason you can’t sleep
- The exact reason you wake up in the middle of the night
- How to lower your heart rate to fall asleep faster
- The truth about supplements like magnesium
- Why sleep quality matters more than sleep quantity
Sleep isn’t a luxury… it’s the foundation of everything.
And when you start to understand your body… you stop fighting it, and start living better.

23. Sarah's Thoughts: What if the things that didn’t work out actually protected you?
05:50||Season 10, Ep. 23Have you ever wondered if the things that didn’t work out… were actually protecting you?In this episode of Sarah’s Thoughts, Sarah Grynberg explores the quiet shift from seeing disappointment as loss to understanding it as something that may not have truly aligned. She reflects on the way we often fall in love with the idea of something, a job, a relationship, an opportunity, and how that imagined version can feel so real that losing it feels like losing something certain.Sarah unpacks why what we grieve is often the story we created, not the full reality we couldn’t yet see. She explores the difference between something that fits and something that requires constant effort to hold together, and how with time, clarity reveals what was once hidden beneath hope and expectation.You’ll learn:Why we attach to the idea of something before fully understanding its realityHow to recognise the difference between alignment and forcing something to workA powerful reframe that shifts disappointment into clarity and self-trustThis episode is an invitation to soften your perspective when things don’t go the way you planned. To allow disappointment without letting it define the meaning of what happened. Because sometimes what falls away isn’t something you lost, it’s something that didn’t fully fit. And the things that are truly right for you won’t need to be forced.Purchase Sarah's book: Living A Life Of Greatness here.To purchase Living A Life of Greatness outside Australia here or here.Watch A Life of Greatness Episodes On Youtube here.Sign up for Sarah’s newsletter (Greatness Guide) here.Purchase Sarah's Meditations here.Instagram: @sarahgrynberg Website: https://sarahgrynberg.com/Facebook: facebook.com/sarahgrynbergTwitter: twitter.com/sarahgrynberg
